Automatic brushless 400KW generator sets pricing, and network conditions, a generator ..

Generator works with three-phase AC synchronous generator generator, mainly by the main stator, a main rotor, exciter stator and exciter rotor, rotating rectifier and automatic voltage regulator and other components. It is a mechanical energy into AC electrical power equipment. Constructional principle diagram generator ① usually the stator three-phase synchronous generator armature, the rotor magnetic pole. The whole process begins with the car driven alternator diesel internal components. Exciter power generator principle is to use the main rotor produces a smaller residual magnetism AC voltage (AC) signal in the main stator. The small AC signal is sent to the automatic voltage regulator AVR, AVR turn it into a rectified current (DC) signal, and added in the excitation of the stator. ② The DC excitation current through the stator generates a magnetic field in the exciter rotor in turn induces an alternating voltage, and transported to the synchronized rotation of the rectifier, the AC voltage which in turn is converted by the rotating rectifier DC. ③ When the DC voltage is present when the main rotor, it creates a powerful than the original remanence magnetic field, which in the main the stator induces a high AC voltage. This high AC voltage ④ circulated through the system described above, and induced a higher DC voltage back to the rotor. Such an approximation of the cycle until a rated output voltage of the generator. At this time, the automatic voltage regulator began to restrict access to the stator excitation voltage, which in turn limits the total output voltage of the alternator. Voltage setpoint from no to the whole accumulation process typically does not exceed one second time is very short, so that the user put into use as soon as possible to meet the requirements. Figure 2.6 is the schematic generator AVR control and self-motivation. AVR is provided by the host of the stator exciter field excitation power, AVR? Make a feedback voltage sensing signal from the host stator winding by controlling the low power of the exciter field, adjust the exciter armature rectifier output power, so as to control the field current host requirements.
